It may not be complicated, but that doesn't mean it's easy. I have a threaded driver whose cog I've been working on for several years without success.
Cog is left-hand threaded, iirc, so clockwise to loosen.
No, it's right hand thread or else it would unthread while pedaling. Track hubs have a left-hand thread
lockring to prevent the
right hand thread track cog from loosening during
back-pedaling, but a lockring isn't needed on a hub with a freewheel mechanism, like the AW.
